To be honest, the regime change in Afghanistan was kind of working, at least that's what it looked to me when I was there in 2010. Then the western world lost interest and withdrew
The right thing is let every country run in their way. Don't interfere. It is wise for U.S. army to withdraw from Afghanistan.
I resent the Taliban for depriving of the right of women to receive eductaion, but that doesn't mean I support meddling in other countries' internal affairs. Believe in Afghanistan will generate an enlightened regime in the future.
